My relationship feel surreal

I've been with my boyfriend for a year and a half and it just feels so surreal at times. In the beginning I just couldn't really believe it because he was so perfect. I've gotten a lot more comfortable, like completely comfortable and I was just thinking about our relationship and how surreal it is to me. He's so attractive and perfect, well not personality wise perfect we have had some issues like all relationships, but overall I feel like it's just so weird that he's dating me. Maybe it's because it's my first real relationship and we've already established that we want to spend our lives together and made plans for the future. Or maybe it's because it is my first relationship and I'm just not used to the commitment, or because he's just so attractive. He's also away for air force bootcamp and I was just thinking about him and how he looks and our memories together and I was just thinking how it all seems like a dream that I can be so comfortable and love someone so much and have them be the same way towards me. Does anyone else get that feeling?
